Assembling the tank dome and telescopic dome shaft

6.1

Assembling the tank dome

Prior to assembly, the enclosed seal is inserted into the tank
domes' groove „B". The tank dome is then aligned with the
piping connections and is locked to the tank neck. It is essential
to make sure that the upper seal "A" is correctly installed.

Assembling the telescopic dome shaft

The telescopic dome shaft enables infinite adaptation of the tank
to given site surfaces with earth coverage of between 750 mm
and 950 mm (Mini telescopic dome shaft) or 750 mm and 1050
mm (Maxi telescopic dome shaft).
For assembly purposes, the enclosed profile seal (material
EPDM) is inserted into the tank dome's sealing groove and is
coated generously with soft soap (do not use mineral oil-based
lubricants, as these attack the seal). The telescope is then
greased, inserted and aligned with the surface of the site.

during this step. The cover is then positioned and is sealed to
prevent entry by children. Tighten the threaded connection
on the cover so tightly that it cannot be opened by a child!

Telescopic dome shaft over which passenger cars may drive

If the tank is installed under areas used by passenger cars, the
collar area of the telescope
supported with concrete
layer of concrete to be installed must be at least 300 mm wide
and approx. 200 mm high all around. The minimum coverage
above the shoulder of the tank is at least 800 mm (max. 1050
mm with telescope, coverage up to max. 1800 mm possible
with intermediate section).
Attention: It is essential to use the cast telescopic dome shaft
(with class B cast cover).
